Dissimilation.—a. λ sometimes becomes ρ when λ appears in the same word: ἀργαλέος painful for ἀλγαλεος (ἄλγος pain).
b. A consonant (usually ρ) sometimes disappears when it occurs also in the adjoining syllable: δρύφακτος railing for δρυ-φρακτος (lit. fenced by wood).
c. Syllabic dissimilation or syncope occurs when the same or two similar syllables containing the same consonant succeed each other: ἀμφορεύς a jar for ἀμφι-φορευς, θάρσυνος bold for θαρσο-συνος. This is often called haplology.
